Colicin Y

Colicin Y is a type of Colicin, a bacteriocin made by E. coli which acts against other nearby E. coli to kill them with its Pore Formation activity in the membrane, leading to depolarisation of the membrane which kills the cell. Very little other information is known about it, such as about the receptor protein it parasitises on the target cell, or the translocation proteins used to translocate it into the cytoplasm.
